Abstract
【解決手段】 同軸ケーブル10は、中心導体10aと、絶縁被覆層10bと、シールド導体10cと、保護被覆層10dとを備えている。ケーブル10の高周波特性を測定評価する際には、まず、同軸ケーブル10の端部に、固化性樹脂の固化体12を形成した後に、ケーブル10の長手方向に対して、直角に切断して直角切断端面14を形成する。次に、同軸ケーブル10の切断端面14に露出する中心導体10aとシールド導体10cとに、コンタクトプローブ20の一方の端部に設けられた測定端子22をそれぞれ接触させる。測定端子22には、高周波特性測定評価装置が接続されているので、この装置を作動させて、同軸ケーブル10の高周波特性を測定評価することになる。
